To all :whom it may concern:

Be it known that I, LUTHER BADGER, a ClillZBIl' of the United States,and a resident of- St. Johns, in the county of Multnomah and State ofOregon, have invented a new and Improved Roller-Bearing, of which thefollowing is a full, clear, and exact description. s

The invention is an improvement in ball or roller bearings, the samebeing designed for general purposes, as, for example, car, locomotive,automobile and other vehicle act-ers. I

Theinvention contemplates an anti-fric tioz'i bearing capable of freeworking under end thrust in either direction, or a lateral strain, asthat occasioned by the weight of the load, the bearing consisting of aninner and outer bearing member and 'aninternally threaded bearingsupport, the inner bearing I member increasing in diameter in passingrom the ends toward the-center and. the outer bearing member composed Oftwo sec tionsthreaded into the bearing support from the opposite sidesthereof.' g

- Reference is to be had to the accompany ing drawings forming a part ofthis specifi cation, in which similar characters of refercorrespondingparts in both views. j

' Figure 1 is a central longitudinal section 'of a bearing constructedin accordance with my invention; and Fig. 2 is an inner face v1ew of thebear1ng, w1th one of the sections of the outer bearing member removed.

More specifically-described, the bearing comprises an inner bearingmember 5, and an outer bearing member composed of two heads or sections6, 6, the inner bearing mem her having the general form of a doublecone. with the enlarged portionat the center and inclining outwardlytoward the center of the bearing in passing toward the ends, and thesections of the outer bearing member each covering one-half of theinner; bearing member and abutting or meeting around the enlargedcentral portion of the latter. Between each side of the inner bearingmember and adjacent section of the outer bearing member are providedannular roller, raeeways 7 arranged in and also machines ofvarious char-1 stepped relation. For this purpose the opposed faces of the twobearing members are stepped, with steps 8 formed in the inner bearingmember 5 intermediateof the steps formed in this member for theraceways, into which project ,the points or angles 9 of the steps of theouter bearing member, prevent the lubricant from from one roller racewayto points or angles of the steps separated when the bearing is that theycannot rub together. For further retaining the oil or other lubricantwithin. the roller or ball raceways, one of the hearing inembers shownin the drawings to be freely passing another, these being slightly withannular ribs 10, arranged at the ends and inwardly of the rollerraceways and fitting within corresponding grooves formed in the othermember.

The bearing has a central bore 11 to receive an axle, shaft or otherlike. device 12 which is suitably fixed to the inner bearing member-'5.The twosections of the outer bearing member 6- are externally threadedand'ea'ch provided with an outer flange 13, the threaded portion of eachsection 6 being screwed into a wheel or other bearing support 14, withthe flanges 13 of the two sections bearing against the opposite faces ofthe wheel and afiixed thereto by bolts 15, the

of the wheel. To give the bearing a finish, each section of the bearingmember is constructed with an outwardly-projecting externallythreadedboss 16 on wardly beveled edge bearing against the bearing section. Ifdesired, the axle or shaft inner bearing-member, leaving a lubricantchamber in the outer section of the outer bearing member.

Having thus described my invention, I claim as new and desire to secureby Letters vl atent: T 7 H f The'combination of inner and outer bearingmembers, the inner member increasing in diameter in passing from theends toward of two sections joining around the enlarged and serving toassembled, -so

the, inner bearing member 5, is constructed which is screwed a cap 17,the cap preferably having an in-- the center, and thetouter membercomposedhearing when thus applied forming the-hub counterpart beveledportion ofv the outer 12 may terminate-at the outer side of the portionof the inner member, said members having the opposed faces thereofstepped to form roller raceways, with the stepped portions of one'ofsaid members projecting into 5 stepped portions of the other of saidmembers arranged intermediate of the raceways. In testimony whereof Ihave signed my name to this specification in the presence of thesubscribing Witnesses.

LUTHER BADGER.
